According to the heat sink of the present invention, the plate-shaped heat dissipating member that contacts the loose body and the curved metal plate are formed into a plurality of heat dissipating fins having a plurality of fins and a plurality of heat dissipating holes, and the like. Since the heat dissipating blade and the coating layer of the heat dissipating member are used, it is possible to realize a heat dissipating heat having a high heat dissipation efficiency which is inexpensive to manufacture by extrusion molding and easy to manufacture. [Embodiment] In the following, a diagram showing an embodiment thereof is shown. Explain the creation. Fig. 1 is an exploded perspective view showing the configuration of the principal part of the embodiment of the heat sink of the present invention. The heat dissipating plate 10 is a plate-shaped heat dissipating member 12 having a heat dissipating surface of a heat dissipating body (not shown) and having a heat transfer surface 12a on the back side of the contact surface. In the heat dissipating member 12, a metal material such as a high-temperature heat conduction f, a lunar b, or the like is used, and on the heat transfer surface 12a, a heat-dissipating surface 12a having a plurality of blades Ma and a plurality of heat-dissipating holes Mb is formed and formed as a heat-dissipating blade M340553 of the panel. On the side of the side. The heat radiating member 12 and the heat radiating fins 14 are individually produced. The heat dissipating fins 14 are formed into a necessary shape by being fitted to the heat transfer surface i2a of the heat dissipating member 12 after forming a plurality of vanes 14a and louvers by, for example, bending the sheet metal sheet for many times. ,size. Next, a heat dissipating plate 1A is formed by combining the surface of the heat dissipating fins 14 and the heat transfer surface 12a of the heat dissipating member 12.
散熱葉片14之剖面之散熱孔14b之開口形狀係例如三 角幵ν’在每次板金加工時而彎曲金屬板四次之際，形成一 個三角形。 另一方面，正如圖2之縱剖面圖以及成為圖2之a__a 之縱剖面圖之圖3所示’在散熱構件12和散熱葉片14之 間三形成用以提高熱傳導效率之錄層16。塗敷層16係塗 敷著石夕膠系、金屬填充物系和塗敷劑系等之散熱脂膏内之 任何一種而形成。 像這樣’在塗敷層16形成於散熱葉片Μ和散熱構件 、之接合面之狀悲下，接合面係無關於其粗糙度而掩埋間 隙進仃密合’因此，提高散熱葉片Μ和散熱構件 之熱傳導性能。 a此外’該散熱板ίο係為了更加地提高散熱構件12 政熱葉片14之結合力，因此，在散熱構件12之端部 ^部U。在本實卿態，爪部13係在方形板狀之散熱構 什12之兩端部，形成為相互地對向，成為抓持散 之構造。在雛態下，於爪部13和散熱葉片14之間 7 M340553 著由於強力接著劑所造成之接合成去3 溶接而進行固定。 力者疋由於銲錫所造成之 以職構造所絲讀熱板1G係正如前蚊敛述，分 別預先個別地製作散熱構件12和散熱葉片14， 複雜構造之散熱葉片14係並非正如a 开止如以在而以擠壓來進行製 :’例如猎由板金彎曲加工而進行製作，因此，製作變得 谷易。The opening shape of the heat dissipation hole 14b of the cross section of the heat radiating blade 14 is, for example, a triangular angle ν', which forms a triangle at the time of bending the metal plate four times each time the sheet metal is processed. On the other hand, the recording layer 16 for improving the heat transfer efficiency is formed between the heat radiating member 12 and the heat radiating fins 14 as shown in the longitudinal sectional view of Fig. 2 and the longitudinal sectional view of the a__a of Fig. 2 . The coating layer 16 is formed by coating any one of heat-dissipating greases such as a Shihic, a metal filler, and a coating agent. Thus, in the case where the coating layer 16 is formed on the joint surface of the heat dissipating fins and the heat dissipating member, the joint surface is not covered with respect to the roughness thereof. Therefore, the heat dissipating fins and the heat dissipating member are improved. Thermal conductivity. In addition, in order to further improve the bonding force of the heat radiating member 12 of the heat radiating member 12, the heat dissipating plate is at the end portion U of the heat radiating member 12. In the present state, the claw portions 13 are formed at the opposite ends of the heat dissipation structure 12 of the square plate shape so as to face each other and become a structure for grasping and dispersing. In the nascent state, between the claw portion 13 and the heat dissipating blade 14, 7 M340553 is fixed by the joining due to the strong adhesive. The entangled hot plate 1G system is the same as the front mosquito, and the heat dissipating member 12 and the heat dissipating blade 14 are separately prepared in advance, and the heat dissipating blade 14 of the complicated structure is not like a start. In order to carry out the extrusion process: 'For example, the hunting is performed by bending the sheet metal, so that the production becomes easy.
